The fractal dimensions of FeZSM-5 zeolites were used to characterize the change in their geometry depending on different postsynthesis treatments. The fractal dimension values were estimated from the Dubinin–Astakhov isotherms of nitrogen adsorption and related to the activity of these zeolites in the benzene hydroxylation to phenol by nitrous oxide. The zeolites had two different iron contents...

In cabbage, glucosinolates such as sinigrin are hydrolyzed by plant myrosinase to allyl isothiocyanate (AITC), allyl cyanide, and, in the presence of an epithiospecifier protein, 1-cyano-2,3-epithiopropane (CEP). Isothiocyanates have been implicated in the cancer-protective effects of Brassica vegetables. The effect of processing on the hydrolysis of glucosinolates was investigated in cabbage. ...

Background for slow steaming A combination of factors have led to the past two years becoming hugely challenging for certain sectors of the global merchant shipping industry. Th ese factors include: Th e downturn in the global economy, resulting in reduced transportation capacity demand Th e substantial global order book for new tonnage, a legacy from the boom years, resulting in record-high de...

this research has been conducted to investigate the influence of steam temperature and densification percentage on withdrawal strength of nail and screw joints as well as flexural strength in compressed wood of eastern cottonwood (populus deltoeides). for this purpose 15 healthy standing trees of eastern cottonwood were selected from dr. bahramnia forest located in shasht-kola (gorgan). the fla...

Modern marine propulsion systems must be reliable, energy efficient, environmentally friendly, and economical. Efforts to reduce fuel costs carbon dioxide (CO2) emissions per nautical mile have a significant impact on the choice of system. Considering that there is no alternative for maritime transport, various technical technological solutions are being considered aim improve efficiency negati...
